"Pronycticebus neglectus" was an adapiformes primate that lived during the middle to late Eocene. One almost complete specimen was found in Hostage Valley, Germany.

Morphology

"Pronycticebus neglectus" possesses a grooming claw on the second digit of each foot like modern strepsirhines (Fleagle, 1999) and had a dental formula of 2:1:4:3. "Pronycticebus neglectus" has a petrosal bulla and a postorbital bar. "Pronycticebus neglectus" may have been a nocturnal or a crepuscular species, which is suggested by a relatively large orbital size. "Pronycticebus neglectus" has a relatively large baculum for a species of its size, which had an average body mass of 825 grams.

Range

"Pronycticebus neglectus" lived on the continent of Europe, in the present country of Germany.

Locomotion

Based upon limb morphology, "Pronycticebus neglectus" moved by quadrupedalism, leaping, and climbing. This species is less of a leaper than the notharctines and used slow quadrupedalism less than the adapines (Fleagle, 1999).
